Busy Philipps has been candid about the ups and downs of following the Whole30 program, and she admitted on her final day of the strict elimination diet that she realized she was completely addicted to sugar.

The 38-year-old actress, who has been using Instagram Stories to update her 763,000 followers on her progress, explained on Tuesday evening that cutting out gluten, dairy, legumes, soy, added sugars, and alcohol forced her to find other ways to deal with her emotions besides eating junk food.

Although she doesn't weigh herself and is unable to give an exact number of how much weight she lost, Busy insisted that she can tell she has slimmed down just by looking at her face.

Success: Busy Philipps has been following Whole30 for the past month. She's pictured on October 16, at the start of the diet (L), and on November 11 (R), 27 days into the program

Restrictive: Busy enlisted her husband, screenwriter Marc Silverstein, to join her in cutting out gluten, dairy, legumes, soy, added sugars, and alcohol for 30 days as part of the program

For her last night on the Whole30 program, Busy ended her diet the same way she started it. The mother-of-two and her husband, screenwriter Marc Silverstein, dined on coconut ginger chicken with zucchini noodles and homemade green sriracha.

Busy asked Marc, who had been following the program with her, to share his opinion on the elimination diet, and he explained: 'It was easier than I thought, but I am glad it's over.'

After putting her youngest daughter, Cricket, to bed, the Vice Principals star gave her advice for successfully starting and completely Whole30, while opening up about the struggles she faced along the way.

'Here's what I learned. Number one, the first week is really hard,' she said. 'Number two, it helps to have a partner, somebody that is doing it with you. Mark was nice enough to do it with me.'

Busy noted that she is not getting paid by Whole30 to promote the program; she just knew a bunch of people who have done it and was curious about it.

'I've never committed to anything like that before, and I thought it would be an interesting thing to do so I did it,' she explained.

'I didn't realize how addicted to sugar I was, and that was really hard for me to get rid of,' she added. 'And I was kind of joking about the cinnamon gummy bears, but also not joking.'

Busy said there was one day when one of her daughter's was 'being a pain' and all she wanted was those gummy bears.

Last day: Busy admitted that the 'first week is really hard,' while her husband noted: 'It was easier than I thought, but I am glad it's over'

Eye-opening: The Vice Principals star said Whole30 made her realize that she was addicted to sugar, and she had to find other ways to deal with her emotions besides eating

'I was like, "Grrr,' she recalled. 'But because I haven't been able to alleviate my feelings through eating food, it's forced me to find other ways to deal, which has been interesting.'

The Cougar Town actress explained that the Whole30 website has a calendar that tells you what you will be feeling on certain days, and she was surprised to see how accurate it was for her throughout the detox program.

Busy admitted that she 'really missed tequila,' adding that it was sometimes difficult to avoid drinking at certain events and social situations.

'I was super bummed on the Baby2Baby [Gala] night because that is one of my favorite evenings of eating and drinking in Los Angeles and I sat it out. But it was also really interesting to not be drunk,' she said with a laugh.

Progress: Busy is pictured on October 19 (L), a few days into the program, and on November 8 (R), in a mustard Madewell ensemble just a week away from finishing the program

Toughing it out: Busy posted this picture of herself with her daughter Cricket on November 5

Countdown: The mother-of-two admitted she was 'annoyed' because she wanted cinnamon gummy bears

'If you want, you can still smoke pot or whatever, but you know sometimes for people pot leads to other decisions that are maybe not Whole 30 approved, like snacks,' she added.

Although she was unable to imbibe, Busy looked phenomenal in a form-fitting, royal blue sequin gown by Jenny Packham.

'I think the thing that everybody really wants to know is how much weight I've lost because I think people are like, "Yeah, but am I going to lose weight?" I think you can see my face — I am definitely smaller. But I don't know how much weight I've lost,' she admitted.

'I don't weigh myself kind of as a thing for me. That's to keep my brain healthy, so I didn't even weigh myself before I started because it doesn't matter to me,' she explained. 'Like a number is a number, and it will drive me crazy, so I can't.'

As for her physical ailments, Busy said the program hadn't really helped with her IBS or spastic colon, which she found fascinating because she was convinced those were food-related ailments.

Making it work: Busy said not being able to drink alcohol or eat the foods she wanted at the Baby2Baby Gala was difficult, but she still had fun with her best friend Michelle Williams

End of it all: Busy posted this photo on Tuesday to celebrate her last day doing Whole30

'There were a few days that were rough': The actress explained in her post that she thought the program would be a good way to get herself on track before the holidays

However, she noted that her joints don't hurt and her knee, which has a pin in it from a previous surgery, hasn't been bothering her.

'I do feel like the inflammation has been down,' she said.

When doling out tips for those who want to try the program, Busy encouraged them to try out Whole30-specific recipes because no one wants to be eating 'plain protein and vegetables.'

She also noted that it's easy to eat clean protein and veggies at restaurants as long as you make sure to tell the waiter 'no butter' — especially if you are getting a steak.

'I wish I could give you a number for weight loss because I feel like that is what people want, but just know that I feel really great. It felt really restrictive the first five days and then after that I was fine,' Busy said in her final video reviewing the program.

'I really enjoyed the Whole30 ultimately, and I think I'll do it again. I am going to try to keep eating really clean and not go off the rails too much — even though [my friend] Steve Agee just wants me to eat candy tomorrow.'
